  Nutrient Support in Hematopoietic Cell Transplantation

  摘要：

  High‐dose cytoreduction and hematopoietic stem cell infusion form the basis for treatment of hematologic cancers, defects or failure of hematopoiesis, and some solid tumors. As an antitumor therapy, allogeneic hematopoietic cell transplantation (HCT) is superior to autologous HCT by induction of a graft‐us‐tumor effect. However, recipients of allografts suffer higher transplant‐related mortality owing to graft‐us‐host disease (GVHD). Nutrition support research must recognize that HCT is a heterogeneous modality whose short and long‐term outcomes are affected by transplant type, preparative regimens, diagnosis, disease stage, age, and nutritional status. The field of HCT will diversify further as lower dose cytoreduction and mixed chimerism grafts allow expansion of the technique to older patients and to other diseases.

  The invention relates to secondary C 10 to C 18 surfactant alcohols of the general formula (I), wherein R represents methyl or ethyl and R′ represents a linear or branched alkyl group with 6-13 C atoms, excepting 5-ethyl-2-nonanol and 6-ethyl-3-decanol, in addition to fatty alcohol alkoxylates, alkyl phosphates, alkyl sulphates, alkyl ether phosphates and alkyl ether sulphates. The secondary C 10 to C 18 surfactant alcohols can be produced by a simple aldol condensation of linear or branched saturated or unsaturated C 7 -C 14 aldehydes, excepting 2-ethyl hexanal, with acetone or methyl ethyl ketone and the subsequent hydrogenation of the condensation product. In the preferred method, the aldol condensation is heterogenically catalysed under hydrogenation conditions and the saturated ketone that has been formed is subsequently hydrogenated. 1

  本发明涉及通式（I）的二级C10到C18表面活性剂醇，其中R代表甲基或乙基，R′代表具有6-13个碳原子的线性或支链烷基，除5-乙基-2-壬醇和6-乙基-3-癸醇外，还包括脂肪醇烷基氧乙基化物、烷基磷酸酯、烷基硫酸酯、烷基醚磷酸酯和烷基醚硫酸酯。可以通过简单的醛缩反应制备二级C10到C18表面活性剂醇，其中线性或支链饱和或不饱和C7-C14醛（除2-乙基己醛外）与丙酮或甲基乙基酮进行醛缩反应，然后对缩合产物进行氢化。在首选方法中，醛缩反应在氢化条件下异相催化，并随后对生成的饱和酮进行氢化。

  It is intended to provide a novel deodorant composition which is excellent in the deodorizing effect, is capable of affording a deodorant composition by a convenient method, and shows no decrease in the deodorizing performance even after a long period of time, once the deodorant being prepared. Specifically, there is provided a deodorant composition containing, as the active component, a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more. As a substitute for a polyphenol, use can be made of a plant extract containing a polyphenol but containing substantially no amino acid. It is also possible to further employ an amino acid. Furthermore, use can be made of a plant extract and/or a plant body containing a polyphenol and an amino acid.

  本发明旨在提供一种新型除臭剂组合物，该除臭剂组合物除臭效果极佳，能够通过简便的方法获得除臭剂组合物，并且在制备除臭剂后，即使经过很长时间，除臭效果也不会降低。具体来说，本发明提供了一种除臭剂组合物，该组合物含有一种有色化合物作为活性成分，该有色化合物可通过在反应 pH 值为 6.5 或更高时，使多酚在与氧分子共存的显碱性溶剂中发生反应而获得。作为多酚的替代品，可以使用含有多酚但基本上不含氨基酸的植物提取物。也可以进一步使用氨基酸。此外，还可以使用含有多酚和氨基酸的植物提取物和/或植物体。
